Functions
template<typename Builder >
std::vector< stdlib::field_t< Builder > >	bb::stdlib::aes128::encrypt_buffer_cbc (const std::vector< stdlib::field_t< Builder > > &input, const stdlib::field_t< Builder > &iv, const stdlib::field_t< Builder > &key)
	Main public interface: AES-128 CBC encryption.
template<typename Builder >
std::array< stdlib::field_t< Builder >, BLOCK_SIZE >	bb::stdlib::aes128::convert_into_sparse_bytes (Builder *ctx, const stdlib::field_t< Builder > &block_data)
	Converts a 128-bit block into 16 sparse-form bytes via AES_INPUT plookup table.
template<typename Builder >
stdlib::field_t< Builder >	bb::stdlib::aes128::convert_from_sparse_bytes (Builder *ctx, std::span< stdlib::field_t< Builder >, BLOCK_SIZE > sparse_bytes)
	Converts 16 sparse-form bytes back to a 128-bit field element.
